The international Long Distance Running Association “Aethlios” was established in 2002 in Athens, according to the 53/2002 Decision of 1st Degree Court of Athens and it is a non-profit association.

The original idea to create an international long-distance race that connects the two of the four important athletic centers of the Panellenic Races of the Antiquity ie the Ancient Stadium of Nemea with that of Olympia, belongs to a small team of people who share their love and expertise in athletics as well as the ancient Greek civilization.
